use the CSC file and not the HOME_CSC.
Note this will wipe your phone

I made it..the csc no the home_csc
I live in greece thats why i download tge eur firmware
In phone info says
Product code:sm-n950fzkaeur
Original csc code:nothing
Firmware's csc code:nothing
Active csc code:eur
Available csc codes:nothing
Csc country:segr/gr
Mobile operator:vodafone gr/20205
Before i made flash in the ative csc was writing dtm and other product code and csc country
I think i made it change or no?

And i go to software information/service provider sw ver. It says
eur/eur/dtm
If i put the note 8 in recovery mode it says multiple csc and active code eur

With this i well get eur ota updates?
So confused

eur/eur/dtm the last CSC will never change as this is hardcoded in the phone firmware.
If the first two are EUR/EUR then you have the correct CSC for OPEN Greece firmware.

Change CSC within multi-CSC

HI everyone,
I have a G970F/DS that has come with XSG firmware and I am trying to change the firmware to XSA
According to the image here https://forum.xda-developers.com/galaxy-s10/how-to/g973f-g973n-multi-csc-firmware-t3903050
For OXM multi CSC
SM-G970FXXU1ASAT-G970FOXM1ASAT
SM-G970FXXU1ASBA-G970FOXM1ASBA
The XSG is in the OXM multi CSC and XSA is in the single - I do not know what this means exactly.
I have tried
Using the *#272*IMEI# code with both IMEI codes, but i do not get a menu after typing it in
Flashing with new firmware from http://updato.com/ with Odin with the sim card in and out
Formatting the device using recovery mode with the sim in and also out+putting it in after
Using Odin to flash VD2 firmware and then back to the OXM firmware
When I flashed VD2 I got VD2/VD2,VD2/XSG in the software information but this went back to XSG/XSG ,XSG /XSG after flashing the OXM firmware
The sim card I am using is an Australian one from Optus and Odin is 3.13.1
Nothing seems to change to XSA.
Am I doing something wrong or is there something else I need to do?
Thanks

You can try inserting a Singapore SIM to see if it triggers Late Customization prompt to reset phone to XSP. 272 menu works in XSP

I don't have a Singapore Sim but I will see if I can get one to try with.
Do I need to reset the phone with the sim in or will the phone ask me when I put the sim in if I want to reset it?
Which IMEI is best to use with 272, does it make a difference?
Thanks for the suggestion

It should prompt you, but you can also try resetting in the recovery menu. I have always used IMEI 1 with 272

Worked for me!!!

WORKED PERFECTLY on my S10!!!
Changed CSC code from ZTO (Brazil retail) to ZVV (Vivo) after flash CHT firmware (from Chile).
I don't know why, but 4g+ from my operator (Oi - Brazil) doesn't work on ZTO -- br retail (it gets only 4g), but in CHT/ZVV it works 4g+ flawlessly!!! Despite Vivo's logo, I'm so happy!

Once you flash a Multi-CSC and your active SIM is within the said list then it would restart and make the changes.
So if you want to move to a different CSC then just use a different SIM that has the specific you need.

SM-G977B - Flash to BTU not working but ODIN Passes

Hey all
Strange one here, i have a SM-G977B (S10 5G on EE UK), i have unlocked it and trying to flash BTU firmware on it via ODIN (download fw from sammobile)
It flashes ok and passes but when phone starts up its CSC is TEL! (Australia!!)
I have re done the flash with XEU and still the same. firmware version says TEL/TEL/EVR in settings
any ideas on this? can this model be flashed to a different region? i want it on BTU not EVR (EE UK)
tried few versions of ODIn too, and left all check boxes default
Thanks

ok, i have reflashed the latest EVR firmware back to the phone and it has taken this fine
Wonder why it doesnt like BTU or XEU?

What firmware files were you trying to flash specifically?
Sounds like you downloaded the wrong one. What are the names of the firmware files you flashed?

Hi
Tried these
https://www.sammobile.com/samsung/firmware/SM-G977B/BTU/download/G977BXXS2ASJ7/299842/
https://www.sammobile.com/samsung/firmware/SM-G977B/XEU/download/G977BXXS2ASJ7/299840/
The above all flash on in Odin, but when the phone starts (even with uk sim in the phone) it defaults to Australia language and 2x Telstra apps install automatically, software info says tel/tel/evr
I then tried this one:
https://www.sammobile.com/samsung/firmware/SM-G977B/VOD/download/G977BXXU2ASJ5/299590/
And the above install the 2x Vodafone uk apps automatically which is fine as I am on Vodafone uk but in software Info is still says vod/vod/evr
What my issue is now is I don’t seem to get 5g on this phone even though I’m on a a 5g contract and has worked previously on a note10+ 5g handset.
Is this handset 5g modem locked to ee?

OK, well I have always had to do that to change CSC via FW flash since the S9 range was released in 2018.
I am waiting for postman to deliver my S10 5G today so will try to flash BTU with OEM Unlock enabled, and let you know the outcome.
(If it doesn't work for me, i will do same as you and flash a network specific FW via Odin - H3G is my network provider).

Yes exactly. My product code is also SM-G977BZAAEVR, so its always going to be an EE UK handset

Hello,
I have the same phone (SM-G977B), I exchanged it with someone in Shanghai (without a box, stupid me)
It was rooted with some CHC firmware (which did not let me download any Google play services), I tried to root the phone (my first time) and ended up re-locking the bootloader.
Later on, while trying different things, I ended up deleting the firmware from TWRP (as I formatted the data, cache folders/directories) as it was not booting up (bootloop on Samsung logo).
Long story short (and rather sad and stupid):
I have a brick phone which has no SD card slot, No OS installed, I do not know the original CSC (except that it was bought in some country in Europe), other firmwares does not flash with Odin (gives me Repartition error failed error), I am unable to mount the device (thought I could transfer the firmware using MTP), I can not change TWRP (downgrade or upgrade) as disk won't mount (for some reasons). I have formatted the disk, changes its format to ext4, ext2 etc.
Any ideas?

I need help about Carrier Switching

A long time ago, I switched my CSC to XAA to use unlocked firmware (no bloatware,...) but I can't use VoLTE on that firmware. Now I want to change my CSC back to Sprint's CSC but my bootloader is now U7, and there is no combination rom for this bootloader.
So is there anyway that I can do to reverse my phone back to default CSC??
Btw, my device is now N950U1, I'm thinking about flash N950U rom but I don't know N950U's CSC is single CSC or multi CSC
Please help me. Thanks in advance

N950u has multi csc but you wont to be able to flash another rom accept the stock and yes you will need to wait till they release the u7 combination only that way you can go back.!!

Question If i remove my sim card and do a factory reset and insert another country's sim card will my phone csc changed to that country's csc?

If i remove my sim card and do a factory reset and insert another country's sim card will my phone csc changed to that country's csc? Because by flashing with odin it doesn't change the CSC

Eeeerm, to my knowledge, this hasnt worked since the introduction of Android 10.
I bought a Vietnam phone csc, and it did not switch to my sim csc.
This method, and the dialer code one are gone.

No it won't. You need to get Samkey account. I also did it with Samkey. Bought phone from another country and change it to mine. I have spare account with credit in it if you are interested.

I'm from Brunei my current csc is Singapore XSP and they release firmware very slow. I wanna change to XME which is malaysia and i have an malaysia sim card with me. I just need the phone to be in XME to receive software updates faster. By formatting and backing up again will take kinda lot of work. Just need a confirmation if i put that malaysia sim card after a factory reset will it change from XSP to XME..

As i said, that didn't even work for me on my Note 9 with Android 10, apparently it worked up to Android 9, but i am not sure about that either.
If i recall correctly, the only time when someone can change the CSC is within a country from Branded (Vodafone i.e.,) to Unbranded, and yet again i am not sure.
I know for a fact that you cannot just CHANGE THE CSC anymore. Not with SIM, not with Odin and not with the dialer codes. If you are on January/February firmware, i think you can still use the dialer code, but you cannot downgrade anymore due to the bootloader incrementation.
Currently your only bet is SamKey, i used it like the other user did too. It's a highly unfair method from a dev that sought the opportunity to make some money. And you need to be on May firmware for that, but luckily you can downgrade as May uses the same bootloader as the latest October build, and that may change very soon.

@emirefek offered you something above. For changing CSC with SamKey, you actually need just 1 credit. The dev does not sell anything under 45 if i recall correctly. On ebay however, people resell 15 of them in one package. It's infuriating but hey, it's the only solution out there.
I did mine from a friend, where he made me share my USB port over the internet. Forgot the damn name of the app but it was mindblowing that something like that exists.

Simple answer. No. But XSP and XME are in the same multi-csc group OXM so you can change by doing the dialer thing. If you look at your software information you will see this line.
XSP/XSP,XSP/XSP/xxx
There 4 csc for phones from XSP. If your phone is directly from samsung ... its xsp but the opetators' phones have different csc.
Xxx will change according to the SIM. But I am not sure if it will allow your phone to OTA according to xxx. I suspect even if you xhange csc this line will be
XSP/XSP,XSP/XME/xxx
The easiest way is to download releases for CSC DBT and odin.

No. But DBT will have monthly updates so DBT will always be ahead of XSP so XSP OTA will be older than DBT.
So if your phone is following dbt releases, you will never ota... with xsp.

You will still get ota. If xsp ota is newer than what is in the phone. But if you keep flashing dbt, the xsp ota is never newer so ota not necessary
